Tornado Watch being issued shortly for MS.
Could we see a pds watch, maybe.

Not PDS.

EDIT: Never mind. SPC must have made a stealth change at the last second, because the initial release wasn't PDS (nor was it mentioned in the mesoscale discussion).

I’d watch this stuff here the hrrr shows later in GA, it’s happened before where the prefrontal supercells way out ahead end up being the ones that do something, not saying this is the case here but that’s something to watch View attachment 39127
Some nasty hooks mixed in there ?
 
So, I did some reading on the supercell tornadoes versus the QLCS tornadoes. As I understand it, the supercell tornadoes are from discreet storms, and are usually the most powerful and longer lasting tornadoes. The QLCS tornadoes come from squall lines and are usually weaker, but can spin up quick and give less warning that a supercell tornado. Does that sound right? Which scenario looks likely for NC tomorrow?
 
40s and rain in the NC mtns. Wedge building for now but winds will rip it apart later. Maybe this area can help disrupt the line before it reaches eastern NC. Timing and cold wedge are hard to predict.
I just don’t think the wedge is gonna hold. We were in the lower 50s in Union county, NC all morning and it’s now jumped to the mid 60s. The stronger wedges that prevent severe weather will typically keep us in the 50s longer

Little bit of both

mid low 50’s here in the upstate. One thing that is concerning is temperatures are expected to rise this evening pushing close to 70 in the early morning hours tomorrow. Warm front lifting? We’ll see if the wedge can hold here. I’m just not sure tbh
